Limas is also accused of murdering the boys’ mother, 31-year-old Arlet Hernandez Contreras. Her body was found dumped in La Puente.

Investigators believe the murders occurred sometime around April 14.

Adams says investigators have already completed a search of a landfill in Brea and began the search of the Irvine landfill after learning that trash from the suspect’s apartment complex is also taken there.
